... which seems a bit pointless. HEx from St Pancras via the Dudding
Hill line I can see, but of course that requires electrification and
perhaps a flyover in Acton. It would be better if it came from Gatwick.

There's not enough space in St Pancras as it is (for Midland main line
services). Also how busy is the Dudding Hill line with freight?

No idea, but a St Pancras to Heathrow service via this route was floated
regularly in the late 1990s.

And it's a bit of a long way round!

It's not ideal but hardly long. It's about two miles longer than the
fairly straight road route from St Pancras to Acton Main Line. Much
quicker than going to Farringdon or Paddington and getting a stopping train.
